Is there a way to format a text in the text element (i.e having bulletin)
Not right now, Yaniv.
But this is on our plan for updates this year. You can vote for a related idea and add it to it here:
A lot has been going on since you wrote. I'm glad to tell you that our current version supports formatting a text in a text UI element. We support the following settings: bold, italic, underline, font color, font size and font family.
Once again, thank you for helping us make Indigo better. If you have any questions or more feedback about the product, we'd love to get your thoughts.
Best regards,ClaudiaIndigo Studio Team
